Roberts is currently dealing with an ankle injury. He missed practice on Wednesday, Thursday and Friday this week, making him somewhat of a longshot to play on Sunday.
Fantasy Impact: Andre Roberts has been an inconsistent fantasy option lately, after getting off to a fast start to the season. This injury only further decreases his chances of making an impact on your fantasy team down the stretch.
Given the state of Arizona's quarterback situation and Roberts' injury, it's safe to drop him for more useful players with the fantasy season in the final weeks.
